2020 Thor Motor Coach Challenger Class A - Gas reviews

The only thing we like about this RV is the layout and the performance of the engine/transmission. We thought we were upgrading earlier this year from our Coachmen Class C but now wonder. The craftsmanship and general engineering from Thor is so bad that I will never own another Thor product. First, the two a/c units cannot keep the unit cool if the temperature is 90 outside. I live in Florida which makes the units unusable at least 4 months of the year. Second, I have had the vehicle for less than 6 months and have it in the shop 5 times so far. Twice for the a/c units not being able to cool the unit and Thor's pathetic response was it is by design. In addition, we have been in the shop three times because the generator will not run for more than 15 mins with only one a/c unit running. This is still not resolved. Another issue we have had is when trying to level the vehicle, occasionally the kitchen slide will not extend because it is rubbing against the wall in the kitchen area. Note this is on fairly level ground. This is an indication that the vehicle was designed without enough rigidity in the frame (poor or complete lack of engineering). Next, when using the furnace, there is a 10 degree difference between the rear of the unit and the front. The fact that Thor cannot layout the ductwork to achieve a semblance of balance in such a small space nearly violates the laws of thermodynamics. Finally, after our third trip, the 50 amp cable provided with the vehicle now needs to be replaced because of the exposed internal wires and poor quality provided by Thor. If you are considering any unit from Thor, I highly recommend NOT BUYING IT! Show less
